I have not seen any code or white paper of how it scales compared to BTC, but it's supposed to scale much better.
I had a nice little mail exchange with their MD. He seems nice enough, but can't disclose anything yet (but sounds eager to do that as soon as possible).
It's currently interbank and financial institutions only, but this might change.
IF accepted and adopted by the central banks, we'll probably see BTC/USD surpassed by BTC/KLX on all major BTC exchanges in volume.
True. This could be huge.
Definitely to be watched.
